抜粋

It is important in maintenance to detect rubbing of sliding bearings in the early stage. An experiment on mild rubbing conditions was conducted, and the changes in vibration were examined. Importantly, a newly found fact is that peaks in the spectral domain with respect to the rotational period occur as a result of rubbing. Consequently, cepstrum analysis was shown to be effective for the detection of rubbing in the early stage. A device that can follow the level of the quefrency was developed based upon this idea. Utilizing the device is a highly efficient way to monitor the condition of a sliding bearing.
